Does anyone know of a good engine repair shop in Oakland County, MI as an alternative to the High Cost Dealership service?

I purchased my CRD new in 2006 and now have 165,000 miles on it. DaimlerChrysler gave me a new engine block, head & turbo at about 36k miles, but since then I have had very few problems. Following advice from CRD Forums, I use good fuel additives in every tank and I regularly run it hard to blow the soot out of it until it burns clean. I generally try to do all my own maintenance but I recently took it to the dealership where I bought it to have it checked out for some issues I felt were beyond my capability. After charging me $440.00 for diagnosis of four (4) issues ($110 each issue....LOL) they reported the following:

1. Needs Timing Belt & Water Pump. This has been on my To Do list for over a year but I don't think I want to pay the dealership $1,900.00 to do it.
2. Turbo-Charger is toast. I suspected this and actually look forward to a much improved unit as recommended on various forums (Suncoast or Mopar Euro). The Dealership estimate was about $4,000.00 for this job.
3. I was very disappointed that the dealership did not know about the air intrusion problem with the suction fuel system. I had to tell them that Mopar has an upgrade kit and they wanted $500.00 for this job. Based upon my research, I am leaning towards putting a pump in the fuel tank as it should have had from the start.

I could probably do most of the work myself but I do not have time. I hope I can find a good diesel engine mechanic to fix all of the above with the Best Available Hardware, plus ECO-Tune, upgraded air intake / filter, Torque Converter upgrade, and possibly some reduction in the factory exhaust restriction. With all of this, I am hoping to get 300,000 miles or so from my CRD. I expect that the cost of all these repairs & upgrades will cost about what the CRD is worth right now, but I am hooked on the TORQUE and it is a pretty solid small SUV. I have had it in some tough spots in the Michigan Deer Hunting woods in winter and it has never let me down.

Thanks in advance for any recommendations! My CRD has been a pretty good vehicle for over nine (9) years and there is hardly a spec of rust on the body and even the under-body is nearly rust free. I would like to keep it alive for my teenage boys to drive for the next several years at least.
